The perimeter is the sum of the side lengths of a shape. A diagonal is a line segment joining two vertices of a polygon or polyhedron when those vertices are not on the same edge. We calculate as follows:

Perimeter = 4a
560 = 4a
a = 140 meters

A=(1/2)d√(4a^2 - d^2)
A = 10240.56 m^2

Please help me with this question

marshall27 [118]

Answer:

80,

Step-by-step explanation:

the way to find the volume of a prism is the following, get 3 measurements, the length, the width and the height (in this case you already have all 3) so simply multiply they together(2*5*8=80)

What is the equation?

zavuch27 [327]

Answer:

$\displaystyle 5x + 6y = 72\:or\:y = -\frac{5}{6}x + 12$

Step-by-step explanation:

Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE RATE OF CHANGES [SLOPES], so 1⅕ becomes −⅚, and we move forward with plugging the information into the Slope-Intercept formula:

$\displaystyle -8 = -\frac{5}{6}[24] + b \hookrightarrow -8 = -20 + b; 12 = b \\ \\ \boxed{y = -\frac{5}{6}x + 12}$

To write this in Linear Standard Form, perfourm he following:

y = −⅚x + 12

+ ⅚x + ⅚x

___________

⅚x + y = 12 [We cannot leave the equation this way, so multiply the equation by the denominatour to eradicate the fraction.]

6[⅚x + y = 12]

$\displaystyle \boxed{5x + 6y = 72}$

I am joyous to assist you at any time.
